Electronic POS Terminals A very monly implemented system, currently being used by numerous restaurants and chains all over the world, is the electronic pointofsale terminal system. Here, the servers/waiters generally take the order from the customer and head onto a terminal, where they can feed the order into a puter. The order can then be transmitted to the kitchen automatically via the terminal through a work, or it may even be delivered manually by the server to the kitchen. Although a huge improvement over the pen and paper still prevalent over the world, this does not have much value addition for the customer and mostly only benefits the establishment and the administration of the establishment. Tablet Based Menu With the current onslaught and popularity of touch based devices, especially the Apple iPad, it did not take long for the tablet based menus to make an entrance in to the market. In their current state, these menus are just a glorified version of their paper based counterparts. The workflow, even with these tablet menus, remains the same as the one mentioned in section or a bination of the previous two. There is very little value addition to the customer and the establishment or its staff. The available technology is definitely not being utilized to its maximum potential. 3. PROPOSED SYSTEM System Architecture The following figure (), demonstrates the basic architecture of our system. Understanding the other intricacies and details of the system will bee a lot easier if one goes through this figure, before diving into the rest of it. Fig Basic System Architecture and System Components The system will consist of the following ponents: The backend, which is made up of the web server and the database, and the frontends that include both the patron frontend (delivered as a native mobile application) and the administration or the kitchen frontend (delivered as a web application). This system is based on the very popular ModelViewController (MVC) architecture. MVC is most monly used in websites, very popular and tried and tested. None of the frontends directly “talk” to the database. They instead rely on RESTFUL web services that can be used to perform CRUD operations on the database. Fig Flowchart The following figure (Fig ) demonstrates the flow of our tablet application. System Overview The most important ponents of this system are the database and the patron frontends or the tablet applications. Providing value to both the business and its patron is an important objective, but we believe that one follows the other. Following that belief, the customer is given a whole lot of importance. The patron will be presented with a tablet, running the Android OS. This tablet will be synchronized with the database running on our centralized cloud powered servers. The menu data, upon synchronization, is stored on locally on the tablets so that the user, . patron, need not wait for the menu to be downloaded from the servers. This will allow faster access to the menu. The user can then browse the menu however they want to, sorting the items on various dimensions like price, popularity, ratings, etc. The user can also click through to view more information about any item like nutritional information, ingredients, trivia and any other content that the restaurant administration may feel like including. The user can also view personalized remendations for items that they may like. This is one of the most important aspects of our system that not only enhances the customer experience but can also help increase revenue for the business. While browsing through the menu, the customer may add items to his/her order. This process is monly known as “building the order”. After the order is built and read, the user may go ahead and place the order. The staff will automatically and almost instantly be notified about the new order so that they can act on it. If the establishment allows, the user may even track the status of their order so that they know when to expect their food and drinks to land up on their table. Remendation Overview The remendation algorithm is an innovative feature that we aim to include in our menu. When most tablet menus provide the customers with only a simple menu, this system will provide remendations which will make it easier to build an order considering what other customers have ordered previously or the similarities between various dishes. Remendation systems using sets were considered . We finally decided to use the below methodology, which has been discussed in an
